# SCStreamFrameInfo

An instance that defines metadata keys for a stream frame.

## Declaration

```swift
struct SCStreamFrameInfo
```

## Overview

Overview Use SCStreamFrameInfo keys to retrieve values from the dictionary of metadata attached to the sample buffers that a stream produces. For example, you can retrieve the display time, content scale, and scaling factor, as shown below: // A dictionary of attachments for a streamed sample buffer. let attachments: [SCStreamFrameInfo: Any] = // Retrieve attachments from a sample buffer.

let displayTime = attachments[.displayTime] as? UInt64 ?? 0 let contentScale = attachments[.contentScale] as? Double ?? 0.0 let scaleFactor = attachments[.scaleFactor] as? Double ?? 0.0
